DS1302+ – Real-Time Clock IC with Trickle Charger – Analog Devices

The Analog Devices DS1302+ is a low-power real-time clock (RTC) IC designed for accurate timekeeping and calendar functions in embedded systems. Featuring battery backup support, trickle charging, and ultra-low power consumption, this reliable component ensures critical timing operations continue uninterrupted during power loss. PCX supplies this industry-standard RTC with guaranteed authenticity and fast shipping.

Key Features

• Precise Timekeeping: Tracks time in 12/24-hour HH:MM:SS format and date in YY-MM-DD-dd.
• Trickle Charger: Automatically maintains backup battery health.
• Ultra-Low Power: Consumes only 0.3µA–1µA during timekeeping (2V–5V).
• Wide Voltage Range: Operates from 2V to 5.5V (main/battery supply).
• Integrated NVSRAM: 31B non-volatile memory for critical data retention.
• Leap Year Compensation: Automatically adjusts through 2100.

Technical Specifications

This through-hole RTC uses a simple 3-wire serial interface for microcontroller communication. Housed in an 8-pin PDIP package (7.62mm width), it operates in commercial temperature ranges (0°C to 70°C). The DS1302+ includes built-in registers for seconds, minutes, hours, day, date, month, and year, with automatic leap-year correction.

Common Applications

• Industrial automation controllers
• Point-of-sale (POS) terminals
• Medical monitoring devices
• Smart meters and utility equipment
• Embedded consumer electronics

About Analog Devices

FAQs

Question: What battery voltage does the DS1302+ support?
Answer: It accepts battery voltages from 2V to 5.5V, compatible with most coin cells or supercapacitors.

Question: How does the trickle charger work?
Answer: The built-in charger periodically replenishes the backup battery, extending its lifespan and maintaining charge.

Question: Is this RTC RoHS compliant?
Answer: Yes, the DS1302+ meets RoHS environmental standards.

Question: Can it operate without a microcontroller?
Answer: No, it requires a host controller to initialize and read/write time/data via its 3-wire interface.

Question: What’s the maximum communication speed?
Answer: While speed depends on implementation, the interface supports standard serial clock rates typical for embedded systems.

Question: Why choose an RTC over software timing?
Answer: Hardware RTCs provide higher accuracy, lower power consumption, and uninterrupted timekeeping during power cycles or sleep modes.
